Adaptions:

• Structural adaptations


  • Adaptations of body shape or body structure
• Functional adaptations


  • Adaptations to the body functions of an organism
• Behavioral adaptations


  • Adaptations to the animals lifestyle or behavior
• Extremophiles


  Organisms adapted to live in very extreme conditions
• Camel adaptations to hot, dry desert

  1. Hump stores fat as insulator

  2. Metabolic reactions produce water from fat

  3. Thick coat insulates from sun heat

  4. Leathery mouth to eat thorny plants

  5. Long eyelashes keep dust out

  6. Can close nostrils to keep dust out

  7. Wide feet prevent sinking in sand
• Camels produce concentrated urine and dry feces to reduce water loss
• Camels can tolerate large changes in body temperature to cope with desert heat
• Kangaroo rat adaptations to desert

  1. Nocturnal to avoid daytime heat

  2. Lives in underground burrows for coolness and protection
• Arctic fox adaptations to cold

  • Thick fur for insulation
  • Fur on paws reduces heat loss
  • Small ears reduce surface area for heat loss
  • Camouflaged coat for hunting
• Cactus adaptations to desert

  1. Small/no leaves to reduce water loss

  2. Spines protect from animals

  3. Extensive shallow roots to catch rain

  4. Can store water in stem
• Extremophiles can live in very high temperatures, pressures and salt concentrations
